A bone cement formulation having i) a PMMA powder fraction designed for quick reaction and ii) a polymerization inhibitor provided in a delayed release form. This allows the cement to obtain an initial viscosity suitable for injection and a long working time.
摘要:
The invention proposes an antibiotic polymethylmethacrylate bone cement that is composed of methylmethacrylate, at least one polymethylmethacrylate or a polymethylmethacrylate-copolymer, at least one polymerisation initiator, such as in radical initiator, at least one polymerisation accelerator, and at least one radiopaquer, whereby the components are present in a powdered component and a liquid monomer component or in two components that are pasty at room temperature. The polymethylmethacrylate bone cement according to the invention comprises the cyclical lipopeptide, daptomycin, a pharmacologically tolerable salt of daptomycin, a solvate and/or a hydrate containing daptomycin and at least one calcium salt, which preferably comprises at least two different release profiles.
摘要:
Compositions and methods, including novel homogeneous microparticulate suspensions, are described for treating natural and artificial surfaces that contain bacterial biofilm, including unexpected synergy or enhancing effects between bismuth-thiol (BT) compounds and certain antibiotics, to provide formulations including antiseptic formulations. Previously unpredicted antibacterial properties and anti-biofilm properties of disclosed BT compounds and BT compound-plus-antibiotic combinations are also described, including preferential efficacies of certain such compositions for treating certain gram-positive bacterial infections, and distinct preferential efficacies of certain such compositions for treating certain gram-negative bacterial infections.
摘要:
Disclosed are methods of delivering an agent to the lumen of the vas deferens under guidance of ultrasound imaging. The methods include vas-occlusive contraception in which the vas deferens is non-surgically isolated and an occlusive substance is percutaneously administered into the lumen of the vas deferens under ultrasound. Also disclosed are methods of reversal of vas-occlusive contraception and methods of delivering an agent to the lumen of the vas deferens. Also disclosed are compositions for use in the methods of the invention.
摘要:
The present invention is directed to a substantially homogeneous miscible liquid adhesive composition comprising a relatively high number average molecular weight (Mn=6,000-10,000 g/mole) multi-arm star polymer having polyisobutylene chains terminated with cyanoacrylate groups (High-Ø(PIB-CA)3); 2-octyl cyanoacrylate (Oct-CA); and a low boiling point biocompatible solvent having a boiling point of not more than 37° C. When this adhesive composition contacted with living tissue and reacted with a nucleophile, such as water or an initiator, the biocompatible solvent will evaporate and the High-Ø(PIB-CA)3 and Oct-CA will co-polymerize in-situ to form a poly(2-octyl cyanoacrylate)-polyisobutylene co-network suitable for any of a number of biomedical applications, from wound closure and healing of skin tissue, to sealant for surgical cuts.
摘要:
The present invention provides a method for making an adhesive composition. An adhesive substrate comprising at least a first cyanoacrylate monomer is provided and then mixed with a thickening agent containing polycyanoacrylate prepared by polymerization of a second cyanoacrylate monomer initiated with an aqueous solution of ammonium hydroxide or alcohol. In light of low boiling point of ammonium hydroxide and alcohol, they can be easily removed by heating at low temperature. As such, conventional premature polymerization of adhesive substrate owing to addition of a thickening agent containing residual accelerators can be overall improved.
